to these of the presses et' Levi Van Heesen and others in use.

The improvement that I have made in the press consists vin suspendingthe 'ulcra E of the levers D to the cap F by the arms G, se as te causethem to swing in the are of a circle described from the center H ofthebolt er peint of suspension ofthe arms toward or from the frame asthe follower rises or falls, the fulcra moving,` outward from the framein the direction of the arrows N o. l as the follower descends, andinward toward the frame in the direction of the arrows No. 2 as thefollower rises, the contraction and expansion of the leversbeingeffected by means of an arrangement o f cords I and pulleys K, appliedto the lower extremities 4of the levers, andswinging,` arms and theweight of the follower, the weight of the follower, in descending,causing` the le` vers to expand, and the drawing of the rope in thedirection ofthe arrow No. 3 causing them to contract and lift thefollower,with the substance thereon to be pressed, which is `pressedagainst the under side of the cap, to

which the fulcra of the levers are suspended, said cap and Vfollowerbeing drawn toward each other as the levers are contracted, compressingthe bale between them, which is tied and removed in the usual manner. Todischarge the bale the foregoing movements of the follower and cap andlevers must be reversed.

All that I claim in the before-described arrangement, and for which Iask Letters Patent, is-

Suspending` the swinging fulera of the pressing-levers ofthe follower tothe head block or` cap of the frame, againstwhich the substance ispressed, in the manner and for the purpose set forth.
